! The American Analyst describes very
| ingenious computing scale, the invention
of Mr.. L.. A. Meneger, of Lansing, Kan.
The scale consists of a simple balance
arm resting Oh a nickel poiut supported by
la standard .SOCut eighteen inches high.
There are two scales CT the taiance arm.
One denotes the weight and total cost of
| the article weighed; the 0ther the unit of
price, which is designated by a sliding
weight. From this sliding weight is sus-
pended the SCOOP OF slab TO contain the
article to be weighed By this scale the
total cost OF any article TO De weighed is
given. For instance, # seven and half
! pounds of butter re placed or the scale,
/ and the price be l51 ceatS pound, the
|! scale shows st once that the total cost is
( Sl.0l4 Or II q purchaser wish Is cents
worth Of tea, the price OF which was 40
cents pound, the weig 1T would De fixed,
| the sliding one as 70 cemts, the other one
( ct the 16 cents mark or TIE computing
scale Then, when enough tea should
heEe been put into the scoop TO cause the
scale to balance, shat qua8tity would
be the Is cents worth desired.
TIE stories once go current, sAst seeds
taken from ancient Egyptisn tombs have
grOWa are believed, il not demonstraoly
false, to lack the guarantees of truth that
tales Of the kind should require; snd
nothing as to the vitality of seeds-can BE-
built upon them. But DR.. LindIey tells
of raspberries that were raised in the gar
dens of the horticultural Society from
seed taken from the stomach OF man who
| was buried in barrow near the tine OF
| the Emperor HadFianT and Professor
! Duchartre and others tell of seeds whose
| identity is properly VoUched for, taEen
from under the foundations OF an OLD
house in Paris, probably from the original
soil of the island, and, therefore, coeVel
with the city, which terminated and
proved to be seeds Of Juncus 0utonlus,.
en- indigenous plant Of that soil.
Some of the features of shorthand
writing. synchrOnOus-mu4tlplex teIe-
graphy and typeWriting are combined IN
| q system of autobiography invented by
NJ. 6. a. Cassagnes, of Paris. In recent
experiments over q wire running from
Paris to Orleans and back, messages were
sent at the rate OF over 200 words
minute, that being the highest speed at
tainable by a nimble-hngered operator.
! By means of an automatic transmitting
apparatus, using q strip OF paper pre-
viouslV perforated, as in some OF the
systems of telegraphy already in vogue,
II 900 words per hour were sent over
line $50 kilometers in length, the messages
being automatically printed BY the receiv-
| ing instrument Science.
| For q green transparent Varnish for
metals, grind small quantity Ct Chinese

powdered chromate of potash ct requires
the most elaborate grinding add sutfi-
cient quantity of copal Varnish thinned
with turpentine. The tone may be altered
by adding more or less OF one or the other
of the ingredients.
Owing to the increased electrical inten-
sity of the atmosphere, which is induced
by the continual evulsiOn of steam and
smoke, DR.. Audries estimates that the
danger from lightning is from three to
five times greater than it was fifty years
! 900.
